Description

  The present invention relates to a polarization image display apparatus used for visually confirming the polarization cutting performance of polarized glasses.

  In general, polarized glasses have a polarizing lens in which a polarizing film is integrally held in a lens material made of glass or plastic in order to remove glare of reflected light (light that has been reflected obliquely on the object surface). I use it.

  Incidentally, the polarizing film is formed by stretching a thin film of polyvinyl alcohol or the like dyed with iodine or a dichroic dye about 3 to 5 times, and orienting the molecules for dyeing to form an optical slit. is there.

  Polarized glasses using lenses that use such a polarizing film are used in high-light environments such as outdoors and other illuminance environments that include polarized light. It is used for fishing in the sea and rivers where there is water, working on fish farms, climbing and skiing, and operating and driving aircraft and cars.

  As indoor use of polarized glasses, in addition to glasses for viewing stereoscopic movies, for example, it may be used to view a latent image that is not visible to the naked eye but hidden on the printing surface (Patent Document 1).

JP-A-9-212389

  However, polarized glasses have almost no opportunity for customers to feel their performance when purchasing, and the ability to cut polarized light is usually available when used in an outdoor environment after purchase. It is often the first time.

  Conventionally, polarized glasses are sometimes used indoors, but they only use the properties of polarized glasses to such an extent that a latent image that cannot be seen with the naked eye is visible. The effect of reducing reflected light cannot be realized indoors.

  In addition, assuming that the light transmitted through the interface between the two substances such as air, water, and glass contains a lot of reflected light, it can be realized that the polarizing glasses can sufficiently transmit the interface and increase the visibility. Indoor display devices are considered to be highly needed by both eyeglass consumers and sellers.

  Therefore, the object of the present invention is to solve the above-mentioned problems and to realize the removal of reflected light as when the polarizing glasses are actually used outdoors when the customer tries on the polarizing glasses indoors. In addition, the performance of polarized glasses capable of selectively transmitting only the light that has passed through the interface without including polarized light is clarified even in the room, and the display device for polarized images can realize the viewing performance of polarized glasses.

In order to solve the above-described problems, in the present invention, a transparent see-through plate is provided on a base so that it can be seen through, and a first image display surface that can be seen through the see-through plate is provided. A second image display surface is provided on the side of the plate to be seen through, so as to intersect the see-through plate at an included angle θ ₂ of less than 90 °, and an image transmitted through the see-through plate of the first image display surface is the see-through image. The first image display surface is arranged so that the polarized image reflected on the fluoroscopic plate on the second image display surface overlaps with the image transmitted through the fluoroscopic plate when viewed with the naked eye from the side of fluoroscopic observation of the plate. The polarized image display device is arranged so as to form an included angle θ ₁ larger than the included angle θ _{2 with} respect to the second image display surface.

  Since the polarized image display device of the present invention configured as described above is provided with a transparent see-through plate supported on the base so as to be seen through, the first image display surface outside the base is transparent. Visible through the board.

At this time, since the second image display surface is provided on the side of the fluoroscopic plate on which the fluoroscopic observation is performed so as to form an included angle θ _{2 of} less than 90 ° with the fluoroscopic plate, the first image is displayed. The image of the light that illuminates the first image display surface appears to be transmitted through the see-through plate and the image (polarized image) that is reflected by the see-through plate on the second image display surface overlaps with the naked eye of the person who is looking. It will be recognized at the same time.

In addition, in order to make the first image display surface visible through the perspective plate from the front of the base or about 1 to 2 m in front of the human eye while maintaining such a state that two images are recognized simultaneously. For this, it is necessary to arrange the first image display surface so as to form an included angle θ ₁ larger than the included angle θ _{2 with} respect to the second image display surface.

  At this time, the image of the first image display surface and the image of the second image display surface appear to overlap with the naked eye, but when a person wearing polarized glasses sees through the polarization lens, the polarization image is cut by the polarization lens. Therefore, only the image on the first image display surface that can be seen through the window plate can be visually recognized, and the wearing feeling of the polarized glasses can be realized.

  Further, in order to make the polarized image appear to overlap the image transmitted through the window plate, and to make it possible to fully feel the wearing of the polarized glasses, the first image display surface described above is a surface on which an outdoor image is displayed. In addition, it is preferable that the second image display surface described above is a surface on which an indoor image is displayed.

  In this way, a state where a person is in the room or in the vehicle and the outside (outdoor) viewed from the window from a relatively bright room (second image display surface) is reproduced, and the reflected light (polarized light) of the window plate is cut from the room. You can feel the wearing feeling of polarized glasses.

  In addition, since the second image display surface is provided with an illuminating device so that the illuminance can be adjusted, the first image display surface can be displayed with light rays that contain a large amount of reflected light when the inside of the window of the display device is viewed. It becomes a display device for a polarization image that can be visually recognized and can realize a function of a device having a superior polarization performance in accordance with the illuminance of the second image display surface.

When the included angle θ ₁ is preferably about 60 to 90 °, the inside of the box can be easily viewed from above the outside of the dark box, and the included angle θ ₂ is about 60 to 85 °. In other words, the polarization performance of the second image display surface can be easily changed and adjusted as necessary.

  In the present invention, when the image is viewed with the naked eye through the fluoroscope, the display device has an image display surface so that the polarized image reflected on the fluoroscope is overlapped with the image transmitted through the fluoroscope. The image that has passed through the plate and the polarized image appear to overlap, but when a person wearing polarized glasses sees through the polarizing lens, the polarized image is cut by the polarizing lens, so only the image that appears to pass through the fluoroscope is visible. There is an advantage that a feeling of wearing the polarized glasses can be realized.

  In addition, the ability to remove polarized light can be realized as if the polarized glasses were actually used outdoors, and the performance of polarized glasses that can selectively transmit only light that does not include polarized light clearly appears. There is also an advantage that a polarized image display device can be realized.
